Problem summary

****************************************************************
* USERS AFFECTED:  All users of IBM WebSphere Application      *
*                  Server Liberty for z/OS                     *
****************************************************************
* PROBLEM DESCRIPTION: An ABEND0C1/ABENDS0C1 occurs when       *
*                      starting a Liberty server.              *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
During Liberty server startup, the server process checks to see
which version of the angel process it is using.  If the address
space containing this Liberty server has been re-used, it may
contain a name token pointing to heap storage that was used by a
previous instance of a Liberty server.  This can occur when the
initial pthread-creating task (IPT) of the new Liberty server
uses the same TCB address as a previous Liberty server.  This is
most likely to occur in a BPXAS address space or a batch
initiator.  It cannot occur when the server is a started task.

Problem conclusion

Code was added to detect when an IPT TCB is re-used in an
address space containing a Liberty server, to avoid the
ABEND0C1/ABENDS0C1.

The fix for this APAR is currently targeted for inclusion in fix
pack 18.0.0.2.  Please refer to the Recommended Updates page for
